Percutaneous retrieval of a twisted guide catheter using a longer second radial sheath

Coronary angiography and percutaneous coronary intervention (PCI) over the radial approach are becoming more frequent and are recommended by the European Association of Percutaneous Cardiovascular Interventions and European Society of Cardiology. The radial approach leads to less bleeding and improved survival in ST‐segment elevation myocardial infarction. Pronounced guide catheter manipulation in cases with tortuous access routes and requirement of extra backup during complex PCI may structurally damage the guide shaft and facilitate twisting and bending. We present three cases where a twisted coronary catheter became stuck in the radial artery and describe a minimally invasive retrieval technique using a second introducer sheath of same French (F) size and greater length. © 2013 Wiley Periodicals, Inc.     

Factor analysis of obsessive-compulsive disorder YBOCS-SC symptoms and association with 5-HTTLPR SERT polymorphism.

Symptoms defining obsessive-compulsive disorder (OCD) are diverse. Factor analyses of OCD symptoms have been used to evaluate obsessive-compulsive phenotypes that are thought to be more homogenous than the macro phenotype. There is evidence that three factors (symmetry/ordering, obsessions/checking, and hoarding) are familial and preliminary evidence that repetitive rituals are associated with a functional polymorphism in the promotor region of the serotonin transporter gene (5-HTTLPR). The goal of this study was to examine relationships between OCD symptom dimensions and 5-HTTLPR. We genotyped 153 subjects who met DSM-IV criteria for OCD. We used the Yale-Brown obsessive-compulsive scale symptom checklist (YBOCS-SC) to assess OCD symptoms. Using principle components analysis, we derived four factors from the 13 symptom categories of the YBOCS-SC in this patient sample, which replicated previous factor analyses of this scale. The frequencies of the S allele and the SS genotype were associated with the second factor including obsessions regarding symmetry and compulsions involving repeating, counting, and ordering/arranging. This study may contribute to understanding of molecular genetic features underlying the appearance of symptom clusters in OCD.

The bacteriology of hidradenitis suppurativa: a systematic review

Hidradenitis suppurativa (HS) is a chronic inflammatory disabling skin disease consisting of recurrent nodules, sinuses, fistulas and scarring involving the intertriginous regions. HS is often a therapeutic challenge and most treatments are off‐label. A better understanding of aetiology and pathogenesis of HS may facilitate the development of effective treatment. Although the clinical presentation is strongly reminiscent of bacterial infection, the role of bacteria remains controversial. Studies have isolated an array of different bacteria specimens. Consistent findings of Gram‐positive cocci and Gram‐positive rods including Staphylococus aureus, coagulase‐negative staphylococci (CoNS) and Corynebacterium species in deep tissue samples have been demonstrated in HS and may constitute a central target for the immune system. Efficacy of antibiotics, that is rifampicin, clindamycin or tetracycline, supports a microbial role in disease pathogenesis. However, these antibiotics also work as immunomodulators of especially T cells, and the underlying mechanisms may therefore be more complex. We performed a systematic review of previous studies investigating the bacterial flora in hidradenitis suppurativa. We searched PubMed, EMBASE, Royal Danish Library and Cochrane library (search date 11 December 2014). A total of 66 papers were identified and nine papers published between 1988 and 2014 matched our inclusion criteria, yielding bacteriological data of a total of 324 patients with HS (mean age 36.8 years and female/male ratio 215/109). This overview of the bacteriology may aid researchers and physicians exploring the potential role of bacteria in HS. Furthermore, to stimulate a broader debate, we also present different viewpoints on the possible role of bacteria in HS.
